Systemic transtiretin amyloidosis in the elderly patient with recurrent pleural effusions

Abstract

Systemic amyloidosis is a group of diseases associated with extracellular deposition of fibrillar proteins, which leads to a loss of normal organ structure and function. Transthyretin amyloidosis occurs with the deposition of amyloid, consisting of transthyretin transport protein, and can be a genetic or degenerative disease of senility (acquired from the deposition of wild-type transthyretin). The article describes the clinical case of transthyretine amyloidosis in elderly patient, manifested by recurrent pleural effusions and biventricular heart failure demonstrating the complexity of timely diagnosis of wild-type transthyretin amyloidosis.
